Ntau lub camcorders thiab txawm tias qee lub xov tooj zoo tshaj plaws suav nrog qee hom duab stabilization thev naus laus zis los txo cov yees duab plooj uas tshwm sim los ntawm kev tuav tes lossis lub cev txav.
Image stabilization yog ib qho tseem ceeb rau txhua lub camcorders, tab sis nws yog ib qho tseem ceeb tshwj xeeb rau cov uas muaj qeeb shutter speeds los yog ntev optical zoom lo ntsiab muag. Thaum lub lens yog zoomed tawm mus rau nws qhov siab tshaj plaws magnification, nws dhau los ua rhiab rau txawm tias qhov kev txav me ntsis.
Qee lub tuam txhab muab lub npe ntawm lawv cov duab stabilization technology. Sony dubs nws SteadyShot thaum Panasonic hu lawv Mega O. I. S thiab Pentax Shake Reduction. Txhua txoj hauv kev nthuav tawm nuances tab sis lawv ua haujlwm tib yam.
Optical Image Stabilization
Optical duab stabilization yog daim ntawv zoo tshaj plaws ntawm cov duab stabilization. Camcorders nrog kho qhov muag duab stabilization feem ntau feature me me gyro-sensors nyob rau hauv lub lens uas sai hloov tej daim ntawm lub lens iav mus rau lub off-set tsab ntawv tsa suab ua ntej daim duab yuav hloov dua siab tshiab rau ib tug digital daim ntawv.
Ib qho duab stabilization thev naus laus zis yog suav tias yog kho qhov muag yog tias nws muaj cov khoom txav hauv lub lens.
Qee lub koob yees duab tso cai rau koj tig kho qhov muag duab stabilization rau thiab tawm, lossis suav nrog ntau hom los them nyiaj rau ntau hom koob yees duab txav (txawm yog ntsug lossis kab rov tav).
Digital Image Stabilization
Tsis zoo li cov tshuab kho qhov muag, cov duab digital stabilization - tseem hu ua hluav taws xob duab stabilization - siv software los txo qhov muag plooj.
Qee lub camcorders xam cov txiaj ntsig ntawm koj lub cev txav thiab siv cov ntaub ntawv ntawd los kho cov pixels ntawm lub koob yees duab duab sensor qhib. Nws siv pixels los ntawm dhau qhov pom thav duab raws li cov lus tsa suab tsis ua kom du ntawm qhov hloov pauv los ntawm tus ncej.
Rau cov neeg siv khoom digital camcorders, digital image stabilization feem ntau tsis zoo dua qhov kho qhov muag. Nws, yog li ntawd, them nyiaj saib ze thaum lub koob yees duab thov kom muaj "duab stabilization." Tej zaum nws tsuas yog ntawm ntau yam digital.
Qee qhov kev pabcuam software siv lub lim kom ruaj khov rau cov yeeb yaj kiab txawm tias tom qab nws raug coj los, los ntawm kev taug qab cov pixel txav thiab kho tus ncej. Txawm li cas los xij, cov txheej txheem no ua rau cov duab me me lossis cov duab ntxiv los sau cov npoo ploj.
Lwm Cov Duab Stabilization Technologies
Txawm hais tias kho qhov muag thiab digital stabilization feem ntau, lwm cov thev naus laus zis sim kho cov yeeb yaj kiab tsis ruaj khov, ib yam nkaus.
Piv txwv li, cov tshuab sab nraud ruaj khov rau tag nrho lub koob yees duab lub cev. Lub gyroscope txuas rau lub cev ntawm lub koob yees duab stabilizes tag nrho cov rig. Cov kws yees duab kws tshaj lij siv cov cuab yeej zoo li no, uas feem ntau hu ua ' steadicam rig, ' txawm li cas los xij, Steadicam yog lub npe hom uas tsim ntau yam stabilizers.
Thiab tsis txhob hnov qab txog txoj hauv kev yooj yim tshaj plaws thiab siv tau yooj yim: koj lub koob yees duab tso siab.
